Zynthian`s sample rate

I understand you are using an instrument from Ableton as reference, is it correct?

Hi @jofemodo !

I have measured how long it takes until a Midi-Note send by Ableton comes back into Ableton as an audio signal from the Zynthian. But I am using an external USB sound card (Steinberg UR22) for sending the MIDI and recording the audio.

@jofemodo

So, the difference should be 2.9 ms. Your measure is slighty more, about twice. Probably it’s a preccission matter. Your “external” latency it too high and it’s difficult to appreciate the difference. What do you think?

Yes I guess that is the thing I learned doing the test - most of the lantency comes from the USB sound card. (output latency + input latency = too much latency). My buffer settings for the USB soundcard are already low. If they where set to even lower values clips and pops are staring to emerge. So I tryed to minimize the Zynthians latency:

Original: freq=44100 =>(2256)/(244100)=5.8ms
New: freq=48000 =>(2128)/(248000)=2.6ms

But it is just a try - I think the original parameters are better in most cases because they are less CPU intensive and it is very likely that I will revert back to them.
